Steps to reproduce:
I tried running the following javascript code:
function* add(x,y) { return x + y; }
console.log(yield { gen: add(yield { gen: add(1, 2) }, yield { gen: add(3, 4) }) })
Actual results:
I get an error in the console that says: "yield expression must be parenthesized"
Expected results:
No error. Sequences are supposed to have higher precedence so the given expression should parse without error.
